CULTIVATOR.

Specification of Letters Patent.

Patented Apr. 15, 1913.

Application filed June 26, 1912. Serial No. 705,932.

To all whom it may concern:

Be it known that I, CHARLES A. PETER- SON, a citizen'of the United States, residing at Ida Grove, in the county of Ida and State of Iowa, have invented a new and useful Improvement in Cultivators, of which the following is a specification.

My invention relates to a double row cultivator, and has for its object a device of this class of simple, durable and efficient construction designed to cultivate at the same time both sides of two rows of corn or other plants.

A further object of my invention is to provide a device of this class with efficient means for raising or lowering all of the plow-beams simultaneously.

A further object of my invent-ion is to provide improved means for connecting the alternate plow-beams together so that the operator can properly cultivate both rows, by watching one row only.

A further object of my invention is to provide means whereby the operator can easily and readily shift the plow-beams from the seat on the cultivator.

The above and other features of novelty, advantages and capabilities of my invention will become apparent from a detailed descri-ption of the accompanying drawings, in which Figure 1 is a plan view of a cultivator embodying my invention and Fig. 2 is a side elevation of the same.

Generally stated my invention consists of a wheeled frame having an arched axle, to which is secured two tongues, which tongues extend backwardly on the axle, and on which the mechanism for supporting and operating the plow beams are mounted. Secured to the tongues forward of the axle is a doubled arch shaft to which is secured in any suitable manner the forward end of the four plow beams. Near the axle is a transverse shaft to which is rigidly secured a series of arms, the outer or free end of said arms being connected to the plow-beams, and secured to said shaft at a suitable place is a lever for rotating said shaft, thus raising or lowering all of said beams simultaneously. Near the rear of the tongues is secured a suitable casting provided with suitable openings, in which is slidably mounted two transverse bars, which bars are connected to alternate plow beams by means of downwardly projecting members, and are so connected as to permit of upward and downward movement of the plow beams with respect to the said downwardly projecting members. Pivotally secured to a cross-brace near the axle are a pair of handles, which are pivot-ally connected near their opposite or free ends to the sliding bars by any suitable means for guiding or shifting the four plows necessary to cultivate two rows of corn. 1

Referring to the accompanying drawings in detail, I have used the reference numeral 10 to designate the arched axle, and 11 the wheels.

12 designates the tongues of the cultivator, which are arranged parallel with each other, and mounted on the axle 10 by any suitable means. Braces 13, 14: and 15 are arranged transversely across the tongues, and are rigidly secured thereto by means of the bolts as shown. These tongues are extended a suitable distance at both ends beyond the axle in order that the draft animals and neck-yokes can be connected to their forward ends while the rear ends of the tongues carry the mechanism for mounting and guiding the plow beams.

Secured on the upper sides of the two tongues, in front of the axle, is a double arch member 16 designed to straddle two rows of corn, which arch member is formed in one piece and bent to form upper and lower horizontal portions. The upper horizontal portions rest on the top of the tongues and are secured in place by any suitable means, such as the straps and bolts shown. The lower horizontal portions are secured to the axle by means of the arm 17 and reinforced and braced to the tongues by means of the upwardly extending diagonal braces 18. Connected to the lower horizontal portions of the member 16 are four plow beams 19 which may be of any suitable con struction. Two of said beams are connected to the outer horizontal portions and two to the central horizontal portions of the member 16. Each of said plow beams is swiveled to the member 16 by means of a stirup 20 and a sleeve 21. Said stirrup is rigidly secured at its rear end to each of said beams ,by'means of bolts as shown and pivotally ing to each beam a univer sal movement. To

facilitate the raising of the plow beams and to counteract the downward movement of the shovels when the cultivator is in operation, I provide a 0011 sprmg which is secured at one end to the plow beams in any suitable manner and at its opposite end to the bracket 23. Said bracket is formed with an integral collar, which .collar is provided with a screw threaded opening deslgned toreceive athumb screw 24, for securing said bracket in place. Said collar is of sufficient size to permit of a sliding movement on the member 16. It will be seen from the construction shown that the said bracket may at their ends with a forked member 27,

formed integrally therewith, to which forked member is pivotally connected a rod 27 at one end and at its opposite end to the plow beams 19 by any suitable means, such as the bolts shown. A lever '29 is rigidly secured at one end of the shaft 25. It will th-us'be seen that by moving the lever in the proper direction all of the beams will be raised or lowered simultaneously as desired. I also provide the lever 29 with the usual engaging means designed to engage a tooth rack 30, for adjusting the lever in any desired position.

Near the rear end of each tongue is rigidly mounted a casting 31, each of said castings is provided with two openings designed to receive the transverse rods 32 and 32*, which rods are connected to alternate plow beams by means of the Vertical rods 33. "Said vertical rods are secured near their upper .ends to the rods 32 and 32 by any suitable means and are connected to the plow :beams at the lower ends in a manner to permit of an upward and downward movement of the plow beams with respect to said rods. For accomplishing this I have shown a loop 34, secured to the rear end of each of said plow beams by means of bolts. Through these loops the rods 33 are inserted. The lower ends of said rods are bent in the form of a circle as best shown in Fig. 2, thus forming a stop 36 for limiting the downward movement of the plow beams. The rods 33 may also be adjustably secured near their upper ends to the rods 32 and 32 so that the .distance between the plow beams may be varied when it is so desired.

For operating or guiding the plow beams from the seat 37 I provide a pair of handles 38 which are pivotally connected at their forward ends to the cross brace 14, by means of the castings and bolts as shown. Said handles are connected near their opposite ends to the two rear vertical rods 33, by means of a pair of short arms 38. The arms 38 are pivotally connected at one end by means of a pin to a suitable casting, which casting is rigidly secured to said handle on the inner side thereof. The opposite ends of said arms are provided with an opening to :receive the upper ends of the rods 33 by which said rods are connected to said handle. The opening in said arms for receiving said rods is of suilicient size to permit said arms to turn horizontally on said rods when the handles are being shifted for guiding the plow beams. It will be seen that the short arms space the handles a short distance apart from the bars 33, thus permitting the handles to be moved transversely of the frame without affecting the connection with said rods. It will also be seen that by having the handles pivotally connected at their forward ends to the frame, a suitable distance from the .operatorand that by having the rear end of the handles terminate at a point near the connection to the bars 33, that it thus perr mits the operator to easily and readily swing the beams a considerable distance,

which is necessary .in the operating of cultivators of this class.

It is necessary in operating m-y cultivator that three draft animals be used, one of which animals travels between the two tongues and one on the outside of each tongue. To equalize the draft among these animals I provide a pair of arms 40, which are spaced apart and secured at one end to each tongue, by means of the bolts as shown. The outer, or free ends of said arms are then brought together to which is pivotally connected the double-trees 41, by means of the pin or bolt 42. It will be seen that the distance from the pin 42 to the point A is equal to twice the distance from the pin 42 to the point B thus equalizing the draft among the three animals lVhile I have herein shown and described only one embodiment of my invention it is to be understood that various changes and modifications may be made by those skilled in the art, without departing from the scope of my invention, as defined in the appended claims.

Having thus fully described my invention what I claim as new, and desire to secure by Letters Patent of the United States is:

1.
